Is RadLab an action? Can I use it to run actions I already own?

RadLab is NOT an action. It actually has nothing to do with actions, and can’t run our actions or anyone else’s. In order to get those nifty, instant previews, we had to build something entirely different, from the ground up. It’s a Photoshop Filter Plugin, technically. RadLab does a lot of the same things actions do, only faster and easier.
